s = "woxiaoe"

print len(s)

print "s[0] " + s[0] + '\t' + 's[1] ' + s[1];

print "s[-1] " + s[-1] + '\t' + 's[-2] ' + s[-2];

print s*10

print 'asS'.isalpha();

print dir(s);

help(s.decode)

msg = '''

print msg

输出

s[0] w s[1] o

s[-1] e s[-2] o

Help on built-in function decode:

decode(...)

S.decode([encoding[,errors]]) -> object

Decodes S using the codec registered for encoding. encoding defaults

to the default encoding. errors may be given to set a different error

handling scheme. Default is 'strict' meaning that encoding errors raise

a UnicodeDecodeError. Other possible values are 'ignore' and 'replace'

as well as any other name registered with codecs.register_error that is

able to handle UnicodeDecodeErrors.
